Image forming apparatus

摘要

The present invention provides an electrophotographic image forming apparatus capable of forming a high quality image by eliminating an expansion/contraction, displacement in color or nonuniformity of color of the image formed on a transfer member (7). An image carrier gear for driving an image carrier (1) is driven by a driving means gear (9) at an image carrier driving position (11a) and transmits driving force to conveying force transmitting gear (8) at a transfer driving position (11b). The conveying force transmitting gear (8) transmits conveying force to the transfer member (7). A time during which the image carrier (1) moves from a latent image forming position (1a) to a transferring position (1b) is equalized almost with a time during which the image carrier gear moves from an image carrier driving position to a transfer driving position.
